An embryo is the early stage of human development in which organs are critical body structures are formed. An embryo is termed a fetus beginning in the 11th week of pregnancy, which is the 9th week of development after fertilization of the egg. A zygote is a single-celled organism resulting from a fertilized egg.

What are the characteristics of the embryonic stage?

What happens during the embryonic period quizlet?

What happens during the embryonic period? Rapid growth and intensive cell differentiation, the organs and major systems of the body form, the genes on the sex chromosomes and hormonal influences also trigger the initial development of the sex organs.

Basic structures of the embryo start to develop into areas that will become the head, chest, and abdomen. During the embryonic stage, the heart begins to beat and organs form and begin to function. The neural tube forms along the back of the embryo, developing into the spinal cord and brain.

What is Germinal Stage?

The germinal stage is the stage of development that occurs from conception until 2 weeks (implantation). Conception occurs when a sperm fertilizes an egg and forms a zygote. A zygote begins as a one-cell structure that is created when a sperm and egg merge.

What are the 3 stages of zygote?

This period is generally divided into three stages: the germinal stage, the embryonic stage, and the fetal stage. The two-week period after conception is called the germinal stage. Conception occurs when a sperm cell combines with an egg cell to form a zygote.

What three things occur during the germinal stage?

Processes in the Germinal Stage. The germinal stage involves several different processes that change an egg and sperm first into a zygote, and then into an embryo. The processes include fertilization, cleavage, blastulation, and implantation.

What happens during the germinal stage?

The germinal period (about 14 days in length) lasts from conception to implantation of the zygote (fertilized egg) in the lining of the uterus. During this time, the organism begins cell division and growth. After the fourth doubling, differentiation of the cells begins to occur as well.

What developmental period is the shortest?
